Description

TECHNICAL FIELD OF THE INVENTION

[0001] The present invention describes a composition of oral administration to prevent and treat degenerative diseases of the eye characterized in that it comprises lysates of probiotic microorganisms in the form of dry powder. Therefore, the present invention is included in the technical field of therapies for degenerative diseases of the eye, particularly age-related macular degeneration (AMD).BACKGROUND

[0002] The average lifespan of the population has increased with the improvement of medical care and the modernization of society. With it, age-related diseases have also increased, making it increasingly evident that aging is an important factor in the development of degenerative diseases. These diseases not only cause central vision loss, but also include those that cause total vision loss such as inherited degenerative diseases of the retina. Among the diseases that are known to be associated with the degeneration of the eye, age-related macular degeneration (AMD), glaucoma, dry eye, etc. stand out. All of them negatively affect the quality of life of the sufferer and health costs. In many cases the mechanisms of the disease are not known although the people with the highest risk of developing them are the elderly.

[0003] AMD is the leading cause of blindness in the over-65-year-old population in industrialized countries. It affects 30-50 million people and despite the introduction of new therapies and prevention, it is expected to increase 10-fold by 2040. Its prevalence increases with age and shares common characteristics with other diseases such as Alzheimer's due to the presence of abnormal extracellular deposits associated with neuronal degeneration, drusen and plaques, respectively.

[0004] Macular degeneration is a disease of the eye, whose most frequent form is the atrophic or dry form, which appears because with age the retina decreases in thickness and the cells of the macula deteriorate, replacing viable cells with trophic areas that when extended can reach the center of the retina, which leads to a slow and gradual loss of vision. Once dry macular degeneration reaches the advanced stage, no treatment can prevent vision loss.

[0005] Although the exact pathogenesis of AMD is not known, exposure to risk factors such as age, genetics, lifestyle, environmental factors and diet is considered to influence its progression. Its development may be due to advanced age and exposure to environmental factors that induce high levels of oxidative stress damaging the macula. This damage causes inflammation inducing a vicious cycle that together causes vision loss. As a defense, the eye has a system of antioxidants formed mainly by vitamins, enzymes and carotenoids that have a synergistic effect and protect themselves in the process of destruction of free radicals. Vitamins C and E, and the carotenoids lutein and zeaxanthin are the most important. In addition, in the retina there is a large proportion of polyunsaturated fatty acids and photosensitive compounds that are highly susceptible to oxidation. These may be involved in the permeability, thickness, fluidity and other properties of the photoreceptors of the membrane, their insufficiency being linked to changes in the function of the retina. With age, the antioxidant system deteriorates due to damage to cellular structures, while the generation of free radicals increases and leads to lipid peroxidation. These peroxides interact with proteins, nucleic acids, and other components that affect the structure of the eye and its function. Degeneration of photoreceptors and accumulation of oxidized metabolites can lead to drusen formation and alterations in retinal pigment (RPE) that can evolve into AMD.

[0006] Because the increase in oxidative damage is one of the main factors, it seems logical to think that the contribution of antioxidants can be beneficial to prevent or slow down the progress of AMD. Diet is the main source of antioxidants providing vitamins, carotenoids, essential fatty acids and trace elements that are usually sufficient for healthy individuals. However, diet alone is not enough to provide the levels needed to protect the eye. In order to restore balance, antioxidant supplements have been proposed as therapy to slow the progression of AMD. One such study that has been conducted, “Age-Related Eye Disease Studies (AREDS) 1 and 2,” has shown that nutritional supplementation with antioxidants and micronutrients can effectively reduce progression to advanced forms of AMD by 28% over a 5-year period in patients over 55 years of age (7). This is currently the most common pre-registration for early and intermediate AMD.

[0007] There are multiple studies and documentations on techniques and methods for the treatment of macular degeneration diseases. Currently, one of the treatments for patients with AMD is intravitreal injections of anti-VEGF drugs, which is the antivascular endothelial growth factor. However, although this treatment is highly effective, it has the technical limitation of being a tedious treatment, that requires the intervention of a specialist in consultation and that can be painful for the patient.

[0008] In other degenerative diseases such as glaucoma, it seems that the mechanism causing vision loss is a consequence of damage to the optic nerve. Most treatments are aimed at controlling intraocular pressure with drugs and surgery, and when treatment is not effective, surgical treatments are used. In any case, the damage caused is not reversible.

[0009] Also in hereditary diseases, such as Stargardt's disease, there is an underlying inflammatory problem that when treated could improve the prognosis or slow down the disease.

[0010] That is why, faced with the technical problem posed by current treatments, the sector is actively working to develop treatments and compositions that can be administered orally to patients. Recently, some studies seem to indicate that the interaction of the microbiota with the eye can influence the evolution of the disease.

[0011] As proof of this, the following patent documents are cited.

[0012] The international patent application WO2022125925A describes methods for treating dry age-related macular degeneration (dry AMD), which includes administering to a subject in need a therapeutically effective amount of a compound or pharmaceutical composition. This method describes a pharmaceutical formulation.

[0013] U.S. Pat. No. 8,603,522B2 describes a daily nutritional or dietary supplement composition that strengthens and promotes retinal health through the prevention, stabilization, reversal and / or treatment of early-age-related macular degeneration. macular degeneration. The ingredients of the composition of the daily nutritional or dietary supplement include vitamin C, vitamin E, lutein, zinc and copper. The ingredients are preferably provided in the form of tablets suitable for oral ingestion.

[0014] The international patent application WO2021224679A1 concerns, in part, methods to prevent or treat macular degeneration in a subject by co-administering an enzyme superoxide dismutase and the probiotic Bacillus sp. spores, especially a mutant strain of Bacillus amyloliquefaciens GF423 or GF424. The present invention also provides pharmaceutical and / or food compositions comprising an enzyme superoxide dismutase and the probiotic Bacillus sp. spores.

[0015] It is also worth mentioning the Spanish patent applications P201930242 and P201930280, patent applications of the inventors, whose content is incorporated here for reference, and which describe a modulating composition of the human intestinal microbiome obtained from lysates of probiotic microorganisms and their method of obtainment, as well as a food supplement comprising the composition, which are useful in the prevention and treatment of disorders caused, or at least encouraged, by intestinal dysbiosis of the microbiota in humans.

[0016] However, none of the documents that are in the state of the art disclose a composition such as that described in this document, that is composed of dry bacterial lysates that allows the reduction and prevention of macular degeneration.

[0017] Therefore, the present invention aims to solve the problems of the prior art by using a composition for oral administration obtained from lysates of probiotic microorganisms for use in the treatment of macular degeneration in humans.BRIEF DESCRIPTION OF THE INVENTION

[0143] To obtain the composition object of the invention, one begins with a set of cultures of the genera described in this document, which comprise a certain amount of Colony Forming Units (CFU). In the context of the present invention, a Colony Forming Unit is a term of microbiology. It is an indicator of the amount of live microorganisms present in a medium.

[0144] In particular embodiments of the present invention, one starts with a number of bacteria of the genus Bacillus comprising between 10.56% to 14.08% of CFU with respect to the total CFU of the composition, most preferably between 11.26% to 12.75% of CFU.

[0145] In particular embodiments of the present invention, one starts with a number of bacteria of the genus Lactobacillus comprising between 29.40% to 68.61% of CFU with respect to the total CFU of the composition, most preferably between 41.17% to 53.36% of CFU.

[0146] In particular embodiments of the present invention, one starts with a number of bacteria of the genus Streptococcus comprising between 5.83% to 31.07% of CFU with respect to the total CFU of the composition, most preferably between 11.65% to 18.15% of CFU.

[0149] These probiotic bacteria are cultured under standard conditions, as set out in the culture protocols published by the Spanish Collection of Type Cultures (CECT), indicated for each of the bacterial species described in this document.

[0150] Once these microorganisms are cultured, they are subjected to a lysis procedure. The process of obtaining lysates consists in combining a non-mechanical method with a mechanical one. Firstly, the microbial cells undergo heat treatment. Each batch of viable cell culture undergoes a sterilization cycle in an autoclave at 121° C. for 20 to 30 minutes. This temperature denatures and coagulates the proteins by inactivating them. It also causes membrane damage, ribosome aggregation, DNA strand breakdown and enzyme inactivation. Once cold, they undergo a cell rupture treatment by sonication for a period of 15 to 20 min, at an output power of between 450 to 550 W, at an amplitude of between 38 to 43% and a period of 8 to 15 seconds of pause, obtaining a mass of lysed cells from the probiotic batch (Qsonica, Q500). This results in the breakage of intermolecular interactions and DNA fragmentation. The final solution is freeze-dried and ground to obtain a lysate of the powdery probiotic microorganism. The powder is stored in a cool environment away from heat.

Certain implementations of the technology are set forth in examples belowPREFERENTIAL EMBODIMENT OF THE INVENTION

[0203] In order to contribute to a better understanding of the invention, and in accordance with a practical realization thereof, we have included as an integral part of this description a preferred embodiment of the present invention.Example 1—Preparation of a Lysate Composition of Probiotic Microorganisms

[0204] The process consists in obtaining the mixture of dry microbial lysates of different strains of Bacillus sp., Lactobacillus sp., Bifidobacterium sp., Streptococcus sp. and Saccharomyces sp. To achieve this, these are grown by fermentation, concentrated, broken up, and finally the cellular components are dried. The postbiotic formulation will be the mixture of lysates that can be accompanied by food ingredients in a capsule or powder supplement format.

[0205] For growth, an inoculum is prepared in a culture medium in a flask of each microorganism, in adequate quantity and volume to be able to proceed to inoculate the fermenter with respective incubated inoculums. To this end, the microorganisms preserved in vials with 20% glycerol at −80° C., are immersed in a water bath at 30° C. to allow a rapid and complete thawing of the respective microorganism.

[0206] Once the inocula of the respective microorganisms have been obtained, the fermenters are sown directly separately. The percentage of planting is 3% for Bacillus species and 5% for each species of Bifidobacterium, Lactobacillus, Streptococcus and Saccharomyces.

[0207] After sowing the fermenter with the inoculum of the corresponding microorganism, we proceed to the fermentation phase of each of the microorganisms for the generation of microbial biomass, establishing the growth conditions for each species.

[0208] For the cultivation of Bacillus, the inoculum is grown in Nutrient Broth (NB) at 30° C. for 15 h at 250 rpm. It is cultured in a fermentation medium composed of Glucose H2O 25 g / l, Yeast extract 5 g / l, K2HPO4 2.5 g / l, MgSO4·7H2O 5 g / l, Tween 80 1 g / l, at 30° C.±1° C. throughout the process and pH 6.8±0.1 by sterile addition of NH4OH 25% or H3PO4 35% automatically. Dissolved oxygen is maintained ≥40% by agitation (150-250 rpm) and aeration (1-1.5 vvm) with a working pressure of 0.5 atm. After approximately 20-24 h, the base consumption (NH4OH) is stopped and the temperature is lowered to 4-8° C. to stop cell metabolism and to harvest the broth.

[0209] In the case of Streptococcus, the inoculum is grown in Tryptic Soy Broth (TSB) to 37° C. at an agitation of 150 rpm for 24 h. The fermentation medium consists of Glucose 25 g / l, milk powder 8 g / l, Yeast extract 5 g / l, K2HPO4 2 g / l, KH2PO4 2 g / l, MgSO4·7H2O 0.5 g / l, (NH4)SO4 0.5 g / l. The growth temperature is 37° C.±1° C. and the pH is maintained at 6.8±0.1 throughout the process by the sterile addition of NH4OH 25% H3PO4 35% automatically. Agitation is 150 rpm. At the end of the fermentation, after approximately 20-24 h, the temperature is lowered to 4-8° C. to stop the cellular metabolism and to harvest the broth.

[0210] The growth of the inoculum of Bifidobacterium and Lactobacillus is made in De Man, Rogosa, Sharpe Broth (MRS Broth) at 37° C. for 24 h. Fermentation is carried out at 37° C.±1° C., Ph 6.2±0.1 and 6.4±0.1, respectively, with the sterile addition of NH4OH 25% or H3PO4 35% automatically, and 50 rpm (the minimum value that guarantees the correct homogenization of the components of the medium) The culture medium is composed of Glucose H2O 20 g / l, Yeast extract 5 g / l, K2HPO4 2 g / l, Casein peptone 10 g / l, Milk powder 8 g / l, Sodium acetate 5 g / l, Diammonium citrate 2 g / l, Mn SO4<sup2>−< / sup2>H2O 0.05 g / l, MgSO4 7H2O 0.2 g / l, Tween 80 1 g / l. Initially nitrogen is bubbled in until the dissolved oxygen concentration is at 0%, repeating the operation whenever necessary to maintain O2 at this level throughout the process. At the end of the fermentation (20-24 h approx), the temperature is lowered to 4-8° C. to stop the cellular metabolism and to harvest the broth.

[0211] The inoculum of S. cerevisiae is grown in YPD for 24 h. In the fermenter the temperature is maintained at 30° C. and Ph 5 at 150 rpm and 1.5 vvm. The fermentation stops in the fermenter itself, lowering the temperature to a value between 4-8° C.

[0212] The recovery of the biomass obtained based on the fermentation of each of the microorganisms is carried out by centrifugation or microfiltration, obtaining wet recovered biomasses, concentrating them as many times as necessary to reach between 1.00E+09 to 1.00E+11 cfu / ml in the concentrated biomasses of each microorganism.

[0213] Subsequently, the rupture or lysis of the cells of each of the wet recovered biomasses is carried out with heat treatment and sonication, obtaining respective bacterial lysates that are subsequently dried separately in a lyophilizer or atomizer. The dry bacterial lysates are mixed in a mixer, to obtain the modulating composition.

[0214] Each batch of viable cell culture undergoes an autoclave sterilization cycle at 121° C. for 20 minutes. Subsequently, they are subjected to sonication for 20 min, at an output power of 500 W with an amplitude of 40% and 10 seconds of pause, obtaining a mass of lysed cells of the probiotic (Qsonica, Q500). The final solution is freeze-dried and ground to obtain a lysate of the powdery probiotic microorganism. The powder is stored in a cool environment away from heat.

[0215] For the analysis of the lysates, 0.5 gr of powder stock is taken from each batch and dissolved in 10 ml of distilled water. A dilution 1:8 is prepared from this suspension (100 sample ul and 700 ul water), and centrifuged for 5 minutes at 5000 rpm. The supernatant is collected, and 1.5 ul of sample is placed in a cuvette to measure the absorbance at 260 nm, 230 nm and 280 nm in a Nanodrop Tecan Spark 10M using distilled water as a blank. The measurement is done at least twice, and it is usual to repeat it more than four times.

[0216] The peak of maximum absorption for the quantification of nucleic acids, DNA, occurs at the wavelength of 260 nm, therefore, at that wavelength, the absorption will be proportional to the concentration of DNA. (ng / ul DNA: A260 nm×dilution factor×50 (conversion factor)

[0217] The amount of DNA present in each of the lysates is as follows:TABLE 2DNA concentrations of each of the dry lysates of bacterial strainsthat were prepared in accordance with the procedure.ProbioticDNA mg / gSDLactobacillus casei13.681.89Lactobacillus acidophilus5.440.85Lactobacillus fermentum3.751.24Lactobacillus reuteri5.960.35Lactobacillus rhamnosus14.721.03Bifidobacterium. lactis3.050.50Streptococcus thermophilus10.711.65Bifidobacterium bifidum7.60Bacillus subtilis6.680.99Bacillus licheniformis5.750.87Saccharomyces cerevisiae12.011.93

[0226] Dissolve 400 mg of the composition of example 1 (hereinafter, Sample) with a chaotropic buffer containing 8.4 M urea (USB Corporation, Cleveland, OH, USA), 2.4 M thiourea (Sigma Aldrich), 5% CHAPS (Sigma Aldrich), 5 mM TCEP (Sigma Alrich) and a protease inhibitor cocktail (Sigma Aldrich), and incubate on ice for 15 minutes. Homogenization was performed by sonication with ultrasonic application for 5 minutes in Branson 2510 bath (Marshall Scientific, New Hampshire, USA). The homogenate was centrifuged at 20000×g at 4° C. for 10 minutes, and the supernatant containing the solubilized proteins was used for further analysis. Consequently, 40 μg of proteins were precipitated by the methanol / chloroform method and resuspended in 40 μg of a UTT buffer (7M urea, 2M thiourea, 10 mM TEAB (sigma Aldrich) of multichaotropic sample solution.

[0227] The resuspended Sample was reduced with 2μ of TCEP 50 mM at 37° C. for 60 minutes, followed by the addition of 1 μL of MMTS reactant (SCIEX, Foster City, CA, USA) cysteine blocker for 10 minutes at room temperature. The Sample was diluted to 140 μl with TEAB mM in order to reduce the urea concentration. Finally, digestion began by adding 2 μg of MS grade Pierce trypsin (Thermo-Fisher Scientific, Inc., Waltham, MA, USA) to each fraction in a ratio of 1:20 (w / w) and incubated at 37° C. overnight in a stirrer. The digested Sample was subjected to evaporation until dryness in a vacuum concentrator.2.2. Liquid Chromatography and Mass Spectrometry Analysis (LC-MS)

[0228] The digested Sample was washed / desalted using Stage-Tips with Empore 3M C18 (Sigma Aldrich) discs. A 1 μg aliquot portion of the resulting peptides was subjected to 1D-nano LC ESI-MS / MS (Liquid Chromatography Electrospray Ionization Tandem Mass Spectrometric) analysis using an Eksigent Technologies nanoLC Ultra 1D plus nano-liquid chromatography system (SCIEX, Foster City, CA, USA) coupled to a Triple TOF 5600 (SCIEX) high-speed mass spectrometer with a Nanspray III source. The analysis column used was an Acquity UPLC M-Class Peptide BEH C18 reverse phase silica-based column (Waters Corporation, Milford, MA, USA). The trap column was a C18 Acclaim PepMap™ 100 (Thermo-Fisher Scientific Inc.), 100 μm×2 cm, 5 μm particle diameter, pore size 100 Å, connected in line with the analysis column. The charge pump supplied a 0.1% formic acid solution in water at 2 μl / min. A flow rate of 250 nL was applied by a nano-pump operated under gradient elution conditions. The peptides were separated using a gradient of 250 min with a B phase ranging from 2% to 90% (mobile phase A: 2% acetonitrile (Scharlab, S. L., Spain), 0.1% formic acid (Sigma Aldrich); mobile phase B: 100% acetonitrile, 0.1% formic acid). The injection volume was 5 μl. Data were obtained using an Ionspray floating voltage of 2300 V, curtain gas 35, interface heater temperature 150, source gas 1 25 and degrouper potential 150 V. For IDA (Intelligent Data Analysis) parameters, a 0.25 s MS scan in the mass range of 350 to 1250 Fa was followed by 35 MS / MS scans of 100 ms in the mass range of 100 to 1800. The change criteria were established for ions greater than a mass / charge ratio (m / z) of 350 and less than m / z 1250, with a charge state of 2-5 and an abundance threshold greater than 90 counts / second (cps). The above target ions were excluded for 15 s.2.3. Analysis of Proteomic Data and Search for Sequences

[0229] The spectrometric data obtained were processed using the PeakView v2.2 (SCIEX) software and exported to mgf files that were searched using Mascot Server v2.5.1 (Matrix Science, London, United Kingdom) against a protein database containing protein sequences of microorganisms of the genera Bacillus, Lactobacillus, Bifidobacterium, Streptococcus and Saccharomyces from the Uniprot / Swissprot knowledge base (https: / / www.uniprot.org / statistics / Swiss-Prot—update: 20170412, 2,542,118 protein sequences), along with commonly existing contaminants. Data were obtained from the total number of coincident peptide spectra for a given protein (referred to as Peptide-to-Spectrum-Matching (PSM) and exponentially modified Protein Abundance Index (emPAI)) for each of the proteins. PSM and emPAI, can be used as a relative quantitative result of proteins in a complex mixture based on protein coverage by matching peptides in a database of results. The LC-MS analyses were carried out at the proteomics facilities of the National Center for Biotechnology of the Higher Council for Scientific Research, which are part of ProteoRed.2.4. Protein Abundances and Functions in the Sample

[0230] The Sample was thoroughly analyzed in terms of the proteins expressed, and 937 proteins were identified. For the 937 proteins identified, spectral counts were obtained to get an indication of their abundance. Normalized emPAI values (nemPAI %) were obtained based on the emPAI values by dividing each individual value by the sum of all empPAI values and multiplying each resulting value by 100%, to obtain the relative abundance of each protein with respect to the total proteins.

[0231] In addition, a functional analysis of the proteins in the Sample was performed by assigning k numbers using the KEGG internal annotation tool for KEGG Orthologies (KO), and searching clusters of orthology groups (COG) to analyze the relative abundance of specific proteins in certain metabolic processes defined in the Kyoto Encyclopedia of Genes and Genomes (KEGG) and COG (http: / / eggnogdb.embl.de / # / app / home).

[0232] FIG. 1 shows the distribution of nemPAI values. As can be seen, the distribution obtained has an exponential shape which indicates the existence of a great diversity of proteins in the Sample.

[0233] The identification of the microbial origin of the Sample was made by a comparative search between the mass spectrometry data of the Sample against the proteins of microorganisms of the genera Bacillus, Lactobacillus, Bifidobacterium, Streptococcus and Saccharomyces of the Uniprot / Swissprot database. The bacterial origins and contribution to the proteome of the Sample are summarized in the following table:TABLE 8Mass spectrometry data of the Sample against the proteins ofmicroorganisms of the genera Bacillus, Lactobacillus, Bifidobacterium,Streptococcus and Saccharomyces from the Uniprot / Swissprotdatabase, where the bacterial origins and contribution to theproteome of the Sample are determined.Number ofRelative number ofRelative proteinGenusproteinsproteins (%)abundance (%)Saccharomyces72777.5987.63Lactobacillus117112.484.69Bacillus758.004.35Streptococcus101.070.33Bifidobacterium30.320.06non-assignable50.530.06Total93799.9897.13

[0234] As can be seen, the microorganisms of the genus Saccharomyces are the ones that contribute the most in terms of the total number of proteins and in terms of the level of expression of proteins contained in the Sample. 10 proteins of the 937 identified with relative abundance of 1% or more correspond to this genus. These proteins and their nemPAI values are identified in the table below.TABLE 9Ten proteins of the 937 identified in theSample with relative abundance of 1%AC ProteinnemPAI (%)E7KMZ64.84A0A0L8VH733.37P0C0X02.34A0A0L8VPY01.76A0A0L8VLA91.52P003591.26E7LV641.16P229431.11P057431.00P213061.00

[0235] Functional analysis based on KEGG orthology (KO) performed to check the functions of proteins in the different metabolic pathways that are defined by KEGG and COG revealed that 643 of the 937 proteins could be assigned to 352 functional categories. Among the notable functions of the proteins with greater abundance is that represented by the category K01689 (enolase [EC: 4.2.1.11]) to which the protein E7LV64 corresponds. This enolase catalyzes the reversible conversion of 2-phosphoglycerate to phosphoenolpyruvate and is essential to the degradation of carbohydrates by glycolysis. Notable functions in the protein profile include K03530 (histone-like binding protein), K13953 (alcohol dehydrogenase) and K03671 (thioredoxin). All of them have a contribution to total metabolic activity of at least 1%.Example 3: Pilot Study to Evaluate the Safety and Efficacy of Oral Postbiotic Therapy in Patients with Secondary Geographic Atrophy in Age-Related Macular Degeneration, Myopia, or Angioid Streaks (Revers)

[0236] This example describes a study that meets the following conditions:

[0237] Open-label, non-randomized study in patients with macular atrophy

[0238] Treatment: postbiotics+antioxidants and vitamins, with the composition of capsule 13.1 Objective of the StudyTo evaluate the growth rate of geographic atrophy according to the transformation of the square root of the area (SQRT) measured in fundus autofluorescence (FAF) with respect to the growth rate of the previous year.

[0240] To assess the safety and tolerability of daily dosing of oral postbiotics assessed by incidence and / or clinically significant changes of a combination of ocular and non-ocular adverse events.3.2 Study Design

[0241] A retrospective review of data from patients participating in the study was conducted, characterizing the progression of geographic atrophy in patients with age-related macular degeneration and another group of patients with similar lesions who did not receive the treatment. The study followed the principles of the Declaration of Helsinki and was approved by the ethics committee of the Teknon Medical Center. Informed consent was obtained from all participants included in the study after explaining the nature and consequences of the study.

[0242] Open-label, non-randomized study in patients with macular atrophy.

[0243] Two groups: Ten patients with moderate-rapid growth (>0.2<0.3 SQRTmm / a) with a known rate of progression, obtained with a previous follow-up of 12 months, to subsequently explore whether the rate of progression slows down 12 months after starting treatment (14 eyes, 9 patients, 1 dropout). The same procedure is performed in a group of ten patients with similar lesions, but without any supplementation (13 eyes, 9 patients)3.3 Results1) The use of oral postbiotics was well tolerated with minimal adverse effects.

[0245] 2) Progression of atrophy:

[0246] After 12 months of postbiotic treatment with sample 1, on average, the eyes showed a 26.58% reduction in lesion growth measured by SQRT compared to the development of the same lesion during the year prior to the start of treatment. Considering only patients with AMD, 10 eyes of 6 patients 19.87% reduction. (See FIGS. 1 and 2.)

[0247] The measurement was performed with two independent gradations using Spectralis Heidelberg's semi-automated region search software.

[0248] The second group of eyes with similar lesions but without treatment did not show this slowing of progression predicted according to their natural history (See, FIG. 3).

[0249] FIGS. 4 and 5 show the areas in SQRT of the groups of patients treated with postbiotics and those not treated, 12 months before and after starting treatment, observing a slowdown of 26.58% and acceleration of 4.5% according to their natural history, respectively.3.4. Conclusions of this Study

[0250] In this pilot study, after 12 months of treatment with the postbiotic, the eyes, on average, showed a 26.58% reduction in lesion growth measured by SQRT compared to the growth of the same lesion during the year prior to the start of treatment, while a control group of eyes (non-randomized) showed a 4.5% increase.3.5. Potential Medical and Socioeconomic Impact of the Study

[0251] The advanced form of age-related macular degeneration (AMD) is the leading cause of blindness in patients over 50 years of age in developed countries, and the most prevalent atrophic form has no treatment. In atrophic AMD there is the death of retinal tissue affecting the central part of the retina, and this area of destruction grows inexorably, increasing its size progressively and in very few years. Today it is a real epidemic that is increasing exponentially, due to the aging of the population.

[0252] Many attempts at clinical trials that have attempted to slow the progression of the disease have failed, due to the very complex multifactorial degenerative character of the disease. Today, a drug based on monthly intravitreal injections is under review by the FDA to assess its approval, with percentages of reduction in the progression of the disease of between 16 and 18% compared to the control group.

[0253] The 12-month REVERS pilot study using oral postbiotic therapy in patients with macular atrophy showed an average slowing of progression of 26.58%, and 19.87% in patients with geographically advanced AMD, compared to the progression that the lesion had shown in the previous year. In a group of patients who were not treated, this reduction was not observed, but on average the lesions grew by 4.5%, close to the linear growth that these lesions are known to have. These results would be in the same range of efficacy as the drugs currently under study and in the approval phase, but with an enormous reduction in the medical and socioeconomic impact, due to it being an oral treatment, compared to monthly injections that must be performed for life. It would avoid both the clinical complications associated with invasive, frequent and chronic treatments, as well as the high socioeconomic costs of all kinds, both for the health system and for patients and their families, which entail these expensive, frequent and ongoing therapies for many years in elderly people.Example 4: Study of the Immunomodulatory Activity of a Postbiotic Composition of the Invention

[0283] The postbiotic composition of the invention was freshly prepared on the day of the assay, directly in the culture medium, following the protocol described above. The composition is as follows:TABLE 10Composition of sample 2 of the composition object of the invention.The percentage by weight of each of the bacterial species comprisingthe dry bacterial lysates described in this document is shown.%SpeciesweightBacillus coagulans1Bacillus mesentericus5Bacillus licheniformis5Bacillus subtilis5Bifidobacterium bifidum2.5Bifidobacterium lactis2.5Lactobacillus acidophilus4Lactobacillus bulgaricus4Lactobacillus casei5Lactobacillus fermentum3Lactobacillus reuteri2Lactobacillus rhamnosus3Saccharomyces cerevisiae55Streptococcus thermophilus3

[0284] THP-1 cells (human monocyte cell line, ATCC® TIB-202) were stored in Gaiker's culture bank and the absence of contaminating mycoplasmas was checked immediately after thawing them. THP-1 cells grow in suspension at 37° C. in a humid atmosphere of 5% CO2. The cells were kept in culture medium (RPMI+10% FBSi+50 μM βmercapthoethanol), for a minimum of two weeks prior to any experiment. Cells were subcultured before reaching 80% confluence (cell / volume concentration).

[0285] A cell suspension of 1×105 cells / mL was prepared 24 hours before the performance of the immunomodulatory activity test. 1×104 cells / well were dispensed in 96-well plates in presence of 0.31 μg / mL PMA to differentiate the monocytes to macrophages. Plates were incubated at 37° C., 5% C02 for 24 hours.

[0286] For the immunomodulatory assay, PMA-differentiated THP-1 cells were incubated with the postbiotic composition of the invention at 15.63 μg / mL for 24 hours in presence of the inflammatory stimulus, lipopolysaccharide, LPS (20 μg / mL). Non-inflamed cells (cells exposed to culture medium without stimulus) were used as a negative test control. The secretion of IL-6, by cells was measured by ELISA means following manufactures instructions. After that exposure time, cell supernatants were collected and analysed. IL-6 has been reported in the state of art as a key player in AMD progression: Droho, S., Cuda, C. M., Perlman, H. et al. Macrophage-derived interleukin-6 is necessary and sufficient for choroidal angiogenesis.
